Answer:

1) Change the length of side AB to 2 feet

Step-by-step explanation:

Given that both structures are similar, it follows that the ratio of their corresponding lengths are equal.

To find out what should be the correct length of AB that she should change to, set up the proportion showing the ratio of 2 corresponding lengths of both structures. Thus:

\frac{PR}{AC} = \frac{PQ}{AB}

We will assume AB is unknown.

PR = 7.5 ft

AC = 2.5 ft

PQ = 6 ft

Plug in the values into the equation

\frac{7.5}{2.5} = \frac{6}{AB}

Cross multiply

AB*7.5 = 6*2.5

AB*7.5 = 15

Divide both sides by 7.5

AB = 2

The architect should change the length of AB to 2 ft

MatroZZZ [7]

Answer:

y-coordinate= 4

Step-by-step explanation:

y+2= -3( x-4) Solve for y

y= -3( x-4) -2

y= -3x +12 -2

y= -3x +10

Now in the given ( _, -2) x=-2

Substitute x= -2 to find the matching y value.

y= -3x +10

y= -3(2) +10

y= -6 +10

y=4

Given y+2= -3( x-4) the missing blank is (4, -2)

Her pay increases $10.00 fore every hour she works

The slope of the line is 10 because you have to pick two points off of the graph, it doesn't matter what two points, and stick them in the formula: y²-y÷x²-x. Once you work out this formula, you get 10/1 which equals to the slope being 10.

The grocery store sells kumquats for $3.75 a pound and Asian pears for $2.25 a pound. Write an equation in standard form for the
sveta [45]

Answer:

3.75k + 2.25p = 14

Step-by-step explanation:

The cost from the weights of kumquats can be represented by 3.75k.

The cost from the weights of Asian pears can be represented by 2.25p.

Using the standard form equation, Ax + By = C, replace Ax and By with these terms.

Then, plug in 14 as C:

Ax + By = C

3.75k + 2.25p = 14

So, the equation is 3.75k + 2.25p = 14
